A light structure for diffuse reflection of light

Abstract

The utility model discloses a diffuse reflection light emitting's lamp structure, include: the light cup, the light cup integral formation one through -going channel, the through -going channel extends to the cup mouth direction, the light source board is set up in the through -going channel is close to the one end of cup mouth, and the light source distribution on the light source board is in the outer periphery side of through -going channel, and the light emitting surface of light source is towards the light cup. Form a through -going channel on the light cup, and distribute the light source on the light source board to the outer periphery side of through -going channel, make the light emitting surface of light source towards the light cup, namely, the light source board flip -chip sets up on the through -going channel, make the light source emit light towards the inside of light cup, and then form diffuse reflection effect by the light cup and reflect the light to the light emitting surface, thereby solve the problem that the conventional lamp adopts direct -down type light emitting and causes glare.

Claims
